Abstract: A container closure includes an outer cap, an inner cap, and a seal. The outer cap includes a top wall and an outer sidewall extending downward from the top wall. The inner cap is secured within the outer cap and includes a bottom wall and an inner sidewall extending upwardly from the bottom wall. The seal is secured to the inner cap and includes a seal sidewall and a rim extending inwardly from the seal sidewall. The seal sidewall sealingly engages the inner sidewall and the rim sealingly overlaps the bottom wall. The inner cap together with the seal define an air pathway in fluid communication between a space between the outer and inner caps and an air opening formed on the bottom wall of the inner cap and selectively covered by the rim.

Abstract: A straw lid valve assembly includes a cap, a spout, and a valve member. The cap connects with a drinking vessel and includes valve receiving passage. The spout connects with the cap and pivots between a drinking position and a closed position. The spout includes an inner passage that is in fluid communication with the drinking vessel when in the drinking position and is closed off when in the closed position. The valve member is receivable in the cap and includes a drink passage and a vent passage in fluid communication with the drinking vessel when the cap is connected with the drinking vessel and the valve member is received in the cap. The valve member is receivable in the valve receiving passage such that an uppermost surface of the valve member is exposed to ambient when the spout is in the drinking position and the valve member is received in the cap.
